HORN.

Application filed October 2, 1926. 'v Serial No. 139,189.

This invention aims to provide a horn, primarily intended for motor vehicles, which sounds a warning consisting of a plurality of musical notes played in a prearrangetl sequence.

Another object of the invention is to provide a horn having removable bushing which controls the sequence of notes played so that by merely removing the bushing and substituting another the tonal sequence may be varied.

A further object of the invention is to provide a horn which can be cheaply manufactured and operated as by a. horn button now in common use.

lith thesek and other objects in view which will become apparent as the specification proceeds, the invention is hereinafter more fully described with the aid of the accompanying drawings, in which:

Figure 1 is a section on the line I-I of Figure 8.

Figure 2 shows an end elevation of the invention.

Figure 3 is a section on the line III- III of Figure 2.

Figure 4 is a section on the line IV-IV of Figure 2.

Figure 5 is a section on the line V-V of Figure 1.

Figure 6 is an enlarged view of one of the horns.

Referring to the drawings, 1 designates a fan housing usually provided with a separate side wall 2 through which are air inlets 3. Attached' to one side of the housing is a casing 4, and 5 indicates a cover secured to the upper end of both the housing and the casing. Bearings 6 and 7 integral with the side wall 2 and casing 4 respectively support a fan shaft 8 on which a fan 9 is arranged.

In the casinfr 4 and secured to the fan shaft S as by a pin 9a is a pinion 10. Bearings 11 and 12 integral with the inner wall of the housing and the casing respectively support an intermediate shaft 13 on which a. gear 14 is secured. This latter gear meshes with the pinion 10. A worm 15 is also ar ranged on the intermediate shaft and cooperates with a worm wheel 16. IThis worm wheel is placed around a vertical shaft 17, and its underside bears against an enlarged portion 18 of the said shaft. The vertical shaft is usually fixed on its underside in a support 19 integral with the casing 4 as by a pin 19, and has a threaded upper end 20 which projects through the cover 5 and has a wing nut 21 screwed thereon.

rihe casing 4, as clearly shown in Figure 4, is bored out to receive a vertical sleeveY 22 which has a plurality of apertures 23 therethrough. As the sleeve turns in the casing each of these apertures in turn register with one of the openings 24 in the casing. The sleeve is substantially concentric with the wormwheel 16 and rests on its hub 25. In order to insure the sleeve turning with the wormwheel pins or projections 26 may be secured to the face of the Vhub to take into corresponding recesses 27 in the underside of the sleeve. ln the openings 24 are couplings 28 the outer ends of` which latter are so directed that the threaded connections 80 of the horns 29 may be kscrewed thereinto without one horn striking the one next to it.

The horns are made in the conventional manner and have reeds 31 therein which vibrate and cause a note to be sounded when air passes through them.

The operation of the device is as follows:

When the shaft 8 is turned the fan 9 rotates and draws air through the inlets 3 and discharges it along the passage inside the cover 5 between the top of the fan housing l and the open upper end of the sleeve 22. At the same time the sleeve is rotated by the wormwheel 16 on which it rests so that the apertures 23 register one at a time with the openings 24 in the casing. As each aperture registers with its opening air passes out through one of the horns 29.

Obviously any desired number of horns 29 of different notes may be provided, and the apertures 23 may be so arranged that the sequence of the notes played may be varied as desired. Moreover by removing the cover 5 the sleeve 22 can be taken out and another substituted having a different arrangement of apertures, so that the tonal sequence may be changed.

lVhile in the foregoing the preferredv embodiment of the invention has been described and shown, it is understood that the construction is subject to such alterations as fall within the scope of the appended claim.

l/Vhat we claim as our invention and desire to secure by Letters Patent is:

A device of the character described comprlsing a housing having a casing attached thereto, a fan rotatably mounted in said housing, said housing and said casing hav- 5 ing a passage therethrough located substanin, a sleeve in said opening having radial 10 apertures therethrough, said casing having radial openings therethrough adapted to register With said sleeve apertures, said sleeve having one open end located at the end of said air discharge passage, means for turning said sleeve When said fan rotates, and a horn mounted in said casing registering With each radial opening therethrough.
